Abstr."],"published-print":{"date-parts":[[2019,6,30]]},"abstract":" \tSince their discovery, carbon nanomaterials (CMs) have been attracting considerable experimental and theoretical interest because of their exceptional structures and properties. Due to their unique structural diversity and the ease of tuning their chemical, electronic and crystalline properties, CMs are attractive for a wide range of electrochemical applications, such as electrocatalysis, fuel cells, batteries and supercapacitors. Also, their properties, such as fast electron transportation, excellent mechanical strength and high surface area, suggest their ability to detect analytes and to promote a fast electron transfer between the electrode and the analyte, which make them promising ECs. CMs have also been presented as effective electrocatalysts that fulfill the requirements for several electrochemical reactions of massive importance in energy conversion systems. Additionally, the possibility of chemical modification and\/or functionalization broadens their utility and gives rise to favourable electrocatalytic properties with regard to several electrochemical processes. <\/jats:p>\n Platinum nanoparticles supported on carbon materials (Pt\/C) are the most effective known ORR\/HER catalysts, leading to low ORR\/HER overpotential, large current densities, and selectivity toward a direct 4-electron pathway in the case of ORR. Nevertheless, the required high Pt loading associated with its high cost, scarcity, declining activity and possible Pt-deactivation by methanol crossover for ORR, have limited the large-scale application of Pt-based ECs. Therefore, research efforts have been devoted to developing alternative ECs, with a competitive activity with the Pt\/C but more stable and cost-effective. In this context, we have developed several ECs (POM@CMs, metal oxides@CMs and biomass-derived CMs) with good electrocatalytic activity towards ORR and\/or HER. <\/jats:p>\n \n Figure 1. <\/jats:bold>ORR by Co4<\/jats:sub>(PW9<\/jats:sub>)2<\/jats:sub>@Carbon material in alkaline medium<\/jats:p>\n <\/jats:p>\n \n \n \n <\/jats:inline-formula>\n <\/jats:p>\n Figure 1<\/jats:p>\n ","DOI":"10.1149\/ma2019-04\/5\/232","type":"journal-article","created":{"date-parts":[[2020,2,27]],"date-time":"2020-02-27T12:27:17Z","timestamp":1582806437000},"page":"232-232","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Carbon Hybrids As Versatile Electrocatalysts for Energy Related Reactions"],"prefix":"10.1149","volume":"MA2019-04","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5263-2737","authenticated-orcid":false,"given":"Diana Mesquita","family":"Fernandes","sequence":"first","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1753-8678","authenticated-orcid":false,"given":"Cristina","family":"Freire","sequence":"additional","affiliation":[]}],"member":"77","container-title":["ECS Meeting Abstracts"],"original-title":[],"link":[{"URL":"https:\/\/iopscience.iop.org\/article\/10.1149\/MA2019-04\/5\/232","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/iopscience.iop.org\/article\/10.1149\/MA2019-04\/5\/232\/pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/iopscience.iop.org\/article\/10.1149\/MA2019-04\/5\/232\/pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"https:\/\/iopscience.iop.org\/article\/10.1149\/MA2019-04\/5\/232\/pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2022,1,27]],"date-time":"2022-01-27T19:27:43Z","timestamp":1643311663000},"score":1,"resource":{"primary":{"URL":"https:\/\/iopscience.iop.org\/article\/10.1149\/MA2019-04\/5\/232"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,6,30]]},"references-count":0,"journal-issue":{"issue":"5","published-print":{"date-parts":[[2019,6,30]]}},"URL":"https:\/\/doi.org\/10.1149\/ma2019-04\/5\/232","relation":{},"ISSN":["2151-2043"],"issn-type":[{"type":"electronic","value":"2151-2043"}],"subject":[],"published":{"date-parts":[[2019,6,30]]},"assertion":[{"value":"Carbon Hybrids As Versatile Electrocatalysts for Energy Related Reactions","name":"article_title","label":"Article Title"},{"value":"ECS Meeting Abstracts","name":"journal_title","label":"Journal Title"},{"value":"paper","name":"article_type","label":"Article Type"},{"value":"\u00a9 2019 ECS - The Electrochemical Society","name":"copyright_information","label":"Copyright Information"},{"name":"date_received","label":"Date Received","group":{"name":"publication_dates","label":"Publication dates"}},{"name":"date_accepted","label":"Date Accepted","group":{"name":"publication_dates","label":"Publication dates"}},{"name":"date_epub","label":"Online publication date","group":{"name":"publication_dates","label":"Publication dates"}}]}}
